Chassis
Designed for 1,550-pound total vehicle payload toughness, the Ridgeline integrates a fully-independent suspension with MacPherson struts in the front and a multi-link with trailing arm design in the rear. The VSA system with active yaw control monitors lateral (cornering) stability and discretely integrates traction control, four-wheel drive, anti-lock braking, throttle control and stability control functions by modulating brake power at each wheel and controlling throttle input. The VSA system is designed to feel smooth and unobtrusive for neutral, predictable and safe handling characteristics.
The heavy duty braking system includes 12.6-inch front and 13.1-inch rear 4-wheel anti-lock disc brakes with Electronic Brake Distribution (EBD) and Brake Assist. Wheels on the Ridgeline RT are 17x7.5-inch steel affairs; the Ridgeline RTS upgrades to alloy. P245/65 R17 all-season tires are standard on the Ridgeline RT and RTS. The Ridgeline RTL is equipped with new-for-2009 18x7.5-inch alloy wheels and P245/60 R18 all-season tires. A standard tire pressure monitoring system (TPMS) provides individual low pressure warnings. A tow hitch becomes standard equipment on every 2009 model and a 7-pin wiring harness is included on the Ridgeline RTS and RTL. The 22-gallon fuel tank provides a maximum highway driving range of up to 373 miles based on the EPA-rated combined city/highway fuel economy and the fuel tank capacity.
Body
The closed-box, unit-body architecture delivers vastly superior rigidity compared to traditional body-on-frame designs and provides the foundation for the Ridgeline's spacious interior cabin and bed, outstanding safety performance and class-leading ride and handling performance.
By choosing a unit body frame with an integrated and fully boxed ladder structure as the base for the Ridgeline, the interior can have more space and the body can be more rigid while containing multiple load paths for enhanced collision energy management. The elimination of traditional body-on-frame construction allows for another feature no other truck product can claim - a spacious In-Bed Trunk with 8.5 cubic feet of secure storage.
Honda's approach to exterior styling on the Ridgeline incorporates a machined billet architecture styling approach for a solid, strong one-piece appearance. No separation between the bed and the cab exists. Designed to appear modern and athletic, the Ridgeline incorporates short front and rear overhangs with integrated bumpers, a large and dominating grille connected to a long and expansive hood, large door handles, and large truck-style side mirrors for good rear vision while towing. The windshield wipers have a heated wiper zone that enhance wiper performance and minimize ice scraping in cold, winter driving conditions.
For 2009, vehicle length measures 207.0 inches, up 0.2 inches due to the new front and rear bumper design. All other key dimensions remain the same: wheelbase 122.0 inches, height 70.3 inches, width 76.3 inches, track front/rear 67.1/66.9 inches, and ground clearance 8.2 inches. The approach, rampover and departure angles (in degrees) measure 24.5, 21.0 and 22.0, respectively.
The cargo area measures 49.5 inches wide between the wheel wells, 20.7 inches deep and 60.0 inches long (79.0 inches with the load-supporting tailgate in the down position). The tailgate is rated to support up to 300 pounds (while the vehicle is moving) and can easily close with contaminates like sand, snow or mud in the space between the bumper and the tailgate.
